Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a quick release clasping device,
and more particularly to a quick release clasping device for rake
or other tools.
2. Description of the Prior Art
Typical rakes or other tools comprise a handle slidably engaged in
a barrel, and a quick release clasping device may be used for
detachably securing the handle to the barrel. U.S. Pat. No.
5,852,923 to Wei discloses one of the typical quick release
clasping devices for the typical rakes which includes a cam lever
engaged with a press piece for forcing the press piece to engage
with and to clamp the handle to the barrel. However, the press
piece is movably received in the barrel and the barrel has no
retaining devices for retaining the press piece within the barrel
such that the press piece may be disengaged from the barrel when
the handle is removed or disengaged from the barrel.
The present invention has arisen to mitigate and/or obviate the
afore-described disadvantages of the conventional quick release
clasping devices for tools.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a
quick release clasping device for a rake or other tools including a
press piece that may be stably retained in the clasping device and
will not be disengaged from the clasping device when the handle is
removed or disengaged from the clasping device.
In accordance with one aspect of the invention, there is provided a
quick release clasping device for a tool, the quick release
clasping device comprising a barrel including a bore formed
therein, and including a pair of flaps extended therefrom, and
including an opening formed therein and communicating with the bore
of the barrel, a handle slidably engaged through the bore of the
barrel, a press piece slidably received in the opening of the
barrel for engaging with the handle, the press piece including a
pair of ears extended therefrom, a lever including a first end
having a cam provided thereon and engaged between the ears and the
flaps and including a second end, and a shaft engaged through the
flaps and the ears and the cam for rotatably securing the cam to
the flaps and for retaining the press piece to the flaps of the
barrel and for preventing the press piece from being disengaged
from the flaps of the barrel.
The ears of the press piece each include an oblong hole formed
therein for slidably receiving the shaft relatively, and for
allowing the press piece to be slid relative to the shaft and the
flaps for a limited sliding movement.
The flaps of the barrel each include a channel formed therein for
slidably receiving the ears of the press piece. The flaps of the
barrel each include a bulge extended outward therefrom for
reinforcing the flaps and for allowing the channels to be formed in
the flaps respectively.
The flaps each include an extension extended therefrom. A device is
further provided for retaining the second end of the lever to the
barrel and includes at least one projection provided on the
extension of the flap, and includes at least one cavity formed in
the second end of the lever for receiving the projection and for
locking the second end of the lever to the extensions of the flaps
and to the barrel. The second end of the lever may be disengaged
from or rotated away from the barrel by engaging the finger into a
space that is formed between the extension of the flaps.
Further objectives and advantages of the present invention will
become apparent from a careful reading of a detailed description
provided hereinbelow, with appropriate reference to accompanying
drawings.

device for the rake; and
FIG. 3 is a partial cross sectional view taken along lines 3--3 of
FIG. 2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, a quick release clasping device in
accordance with the present invention may be attached to the rakes
or the other tools, and comprises a base 30 including a barrel 31
provided thereon, a number of rake tines 40 having one end
pivotally secured to the base 30, a rod or a handle 50 slidably
engaged through the bore 311 of the barrel 31 and including a
bracket 60 attached thereto for threading with the rake tines 40
and for opening or closing the tines 40 by moving the bracket 60
toward and away from the base 30. The quick release clasping device
in accordance with the present invention is provided for clasping
the handle 50 to the barrel 31.
The barrel 31 includes a seat 32 provided thereon and having a pair
of flaps 321 extended from the barrel 31 and preferably parallel to
each other. The flaps 321 each include a channel 322 formed
therein, and each include an orifice 327 formed therein and
communicating with the channel 322 thereof respectively. The flaps
321 each include a bulge 326 extended outward therefrom for
reinforcing the flaps 321 and for allowing the channels 322 to be
formed within the flaps 321. The barrel 31 includes an opening 323
formed therein and formed between the flaps 321 and communicating
with the channels 322 of the flaps 321 and communicating with the
bore 311 of the barrel 31. The flaps 321 each include an extension
324 extended therefrom and each having a projection 325 extended
therefrom. A space 328 may be formed and provided between the
extensions 324 of the flaps 321.
A press piece 33 is slidably received in the opening 323 of the
barrel 31 and includes a pair of ears 331 slidably received in the
channels 322 of the flaps 321. The ears 331 each include an oblong
hole 333 formed therein for aligning with the orifices 327 of the
flaps 321. A shaft 35 is engaged through the orifices 327 of the
flaps 321 and through the oblong holes 333 of the ears 331, such
that the press piece 33 may be retained to the barrel 31 and will
not be disengaged from the barrel 31. The shaft 35 may be slid
along the oblong holes 333 of the ears 331 relatively such that the
press piece 33 may be slid relative to the barrel 31 for a limited
sliding movement. The press piece 33 includes a curved recess 332
formed in the upper portion thereof and formed between the ears 331
and includes a curved depression 334 formed in the bottom thereof
for engaging onto the handle 50.
A lever 34 includes a cam 341 formed or provided on one end thereof
and engaged between the ears 331 of the press piece 33 and having a
hole 343 formed therein for rotatably receiving the shaft 35 and
for rotatably securing the lever 34 to the flaps 321 of the seat 32
of the barrel 31. The cam 341 is engaged on the curved recess 332
of the press piece 33 and may be used to force the press piece 33
to engage with and to force against the handle 50 when the cam 341
is rotated relative to the barrel 31. For example, when the lever
34 is pressed toward and to engage with the barrel 31 at the lock
position as shown in FIGS. 2 and 3, the cam 341 may force the press
piece 33 to engage with the handle 50 and to clamp the handle 50 to
the barrel 31. When the lever 34 is rotated away from the barrel 31
about the shaft 35 to a release position, the cam 341 may release
the press piece 33 from the handle 50 such that the handle 50 may
be slid along the barrel 31 at this time. The lever 34 may include
one or more cavities 342 formed therein, particularly formed in the
other end distal to the cam 341, for receiving the projections 325
of the extensions 324 of the flaps 321 and for retaining the lever
34 to the barrel 31 at the lock position. The other end of the
lever 34 may be moved or rotated away from the barrel 31 by
engaging the finger of the user into the space 328 that is formed
between the extensions 324 of the flaps 321.
It is to be noted that the press piece 33 may be stably retained in
the channels 322 of the flaps 321 and in the opening 323 of the
barrel 31 and thus will not be easily disengaged from the flaps 321
of the seat 32. In addition, the press piece 33 may be stably
retained to the flaps 321 of the seat 32 and the barrel 31 by the
shaft 35, such that the press piece 33 will not be disengaged from
the flaps 321 of the seat 32 and the barrel 31 even when the handle
50 is removed or disengaged from the barrel 31 of the base 30.
Accordingly, the quick release clasping device in accordance with
the present invention includes a press piece that may be stably
retained in the clasping device and will not be disengaged from the
clasping device when the handle is removed or disengaged from the
clasping device.
Although this invention has been described with a certain degree of
particularity, it is to be understood that the present disclosure
has been made by way of example only and that numerous changes in
the detailed construction and the combination and arrangement of
parts may be resorted to without departing from the spirit and
scope of the invention as hereinafter claimed.
